| In the evening of November 15, 1977, a 13-year-old secondary school girl, Ms.YOKOTA Megumi, vanished somewhere hundreds meters away from the seashore, after parting from one of her friends on her way home from school in Niigata City. She has not yet been found since then.
The Japanese police interviewed the persons concerned for the situation, obtained the information in the neighborhood, and compared this case with a similar one. In addition, the former North Korean agent who defected to South Korea was questioned, and exchange of information was conducted with the authorities and agencies concerned. As a result of these required investigations, it is believed that she was abducted by North Korea, and then taken to North Korea
